Specification of Letters Patent.

Eatented June 3, 1919.

Application filed June 24, 1918. Serial No. 241,575.

To all whom it may concern:

Be it known that I, Eanns'r B. Gns'rorson, a citizen of the United States, residing at Anoka, in the county of Anoka and State of lviinnesota, have invented certain new and useful in'iprovements in Gearings, of which the following is a specification.

This invention relates to gearing for cylinder washing machines and the object of the invention is to provide simple and compact gearing" whereby the cylinder of the machine will be given. two complete revohrtions in one direction and then two complete revolutions in the opposite direction, the driving shaft rotating continuously in one ,lirection. A further object of the ii'lvention is to simplify the means by which the driving shaft is thrown into or out of operative connection with the shaft of the Washing machine cylinder, and other incidental objects of the invention will appear in the course of the following description.

The invention is illustrated in the accompanying drawings in which Figure 1 is an end elevation of a washing machine having my improved gearing applied thereto;

Fig. .2 is a plan view of one end of the tub with the gearing in position thereon;

Fig. 3 is an elevation of a portion of the v train of gearing;

Fig. 4 is a detail view of the frame;

Fig. is a detail of a portion of the masler gear;

Fig. 6 is a detail view of the gearing by which the driving shaft is operatively conlittted with the master gear.

lhe washing machine tub I of the usual dimensions and is supported at its end by a frame having legs or standards 2 which also supports the gearing by which the cylinder is caused to rotate within the tub. The standards are connect d by 'an arcuate flange or web 10 which fits under and is secured to the end of the tub and is provided at its center with a hollow projection 41 to which a discharge pipe may be fitted. Upon the outer side of the fran'ie, at the rear thereof, I secure a bracket or frame 3 having an outer arm 4: the upper end of which coacts with a cap plate 5 to provide a bearing for the outer end of the driving shaft (3, a single band pulley 7 being secured upon the said shaft and a belt 8 being trained around the said pulley so as to impart motion there- .to from any convenient engine or prime mover. Upon the inner portion of the drivingshaft 6, I secure a gear 9 which meshes with a gear 10 loosely mounted upon a stub shaft 11. extending between the branches 12 of a lever or swinging arm 13 which is fulcrumed at its rear end 14 upon the frame orln'acltet The frame is provided at its rear edge. with an upstanding post or plate 1-2 to which the bracket 3 may be secured in any convenient manner and at the upper end of which is a socket or hearing 43 for the inner end of the driving shaft (3. A pinion 15 is also mounted on the shaft 11 and is fast to the gear 10. this pinion 15, when the device is in operation, meshing with the external gear 16 on the periphery of the mastor gear wheel 17. The master gear .wheel is loose upon a stub shaft lsiextending from the bearing -11 at the apex of the frame. Upon its inner face, the master gear 17 can ries an arcuate internal rack 19, which as th gear rotates, will mesh with and drive the pinions 20 and E21 alternately. These pinions 20 and 21 are disposed at substantially diametri-cally opposite points with respect to the cylinder shaft and are secured upon shafts 22 and 23, respectively, which are mounted in bearings at the upper ends of arms, shown at 45, on the frame 2. Coaxial with and fixed to the pinions 20 and 21, respectively, are gears 24 and 25, the gear 24 meshing with an idler 26, which, in turn, meshes with the gear 27 fixed to the cylinder shaft, while the gear also meshes with said gear 27. The cylinder shaft extends through the end of the tub in the usual manner and the extremity -16 of the shaft is disposed at the outerside of the gear 27 and journaled in. the hearing i4: as indicated by dotted lines in Fig.

The lever or fork 13 has one of its branches projecting inwardly from the bracket I or frame 3 and is equipped with a guide arm 28 extending downwardly in front of the said bracket or frame 3. An angle lever 29 is pivoted to the lever 13 and the depending branch of this angle lever carries a bolt 30 which is slidably fitted in the guide arm 28 and is adapted to engage a suitable socket or opening in the frame or bracket 3, whereby the lever 13 and the gearing carried thereby will be held in the operative position. A. spring 31 is disposed between the front ends of the lovers l3 and 25) so that the the gears 9, 10, and to the master gear 17,

as will be readily understood. The rack 19 on the master gear will be in mesh with one or the other of the pinions 20 and 21 during practically the entire rotation of the master gear but the extent of the rack is preferably a trifle less than one-half the peripheral extent of the master gear so that 'the rack will leave one pinion before 1t meshes with the other pinion and will thereby avoid breakage of parts due to an attempt of the cylinder shaft to rotate in opposite directions simultaneously. hen the rack meshes with the pinion 20, the motion will be transmitted through the gears 24 and 26 to the cylinder gear 27 and said gear 27 will, consequently, rotate in one direction but when the rack is in mesh with the pinion 21, i

the motion will be transmitted through the gear directly to the gear 27 without the interposition of an'idler and the said gear .27 will, therefore, rotate in a direction opposite to that derived through the idler 26;

VI hen it is desired to stop the operation of the machine in order to change the contents of the tub or for any other purpose, the hand lever 29 is pressed upwardly against the tension ofthe spring 31 and the bolt or latch is thereby withdrawn from the frame 3 so that the lever 13 may be swung rearwardly and the gear 15 moved out of mesh with the gear 17. The shaft (3 may then be permitted to continue its motion or the motor may be stopped may be more economical or desirable, but it is not necessary to stop the rotation of the driving shaft 6 in order to stop the machine nor is it necessary to reverse the direction of the rotation of said shaft in order to reverse the motion of the washing machine cylinder. My improved mechanism is exceedingly simple and compact and may be readily applied to any machines now posed coaxially with the master gear, gears at opposite sides of the driven gear to be engaged by the rack, intermediate gears between the said gears and the driven gear whereby the driven gear will be caused to rotate alternately in opposite directions, a driving shaft, means for rotating the driving shaft continuously in one direction, and means for operatively connecting the driving shaft with the master gear or disconnecting it therefrom.

2. The combination of a master gear, a driven gear, operative connections between the master gear andthe driven gear whereby the driven gear will be caused to rotate alternately in opposite directions as the master gear rotates continuously in one direction, a driving shaft, agear upon the driving shaft, a support adjacent the driving shaft mounted to swing in a plane parallel with the plane of the master gear, idler pinions carriedby said support and arranged be w nd adapted to operatively connect the gear on the driving shaft with the master gear, and means for retaining said swing ing support in the operative position.

The combination of a main support, a bracket thereon, a driving shaft mounted in the bracket, a gear on the driving shaft, a master gear mounted loosely on the main support, a driven gear on the main support, intermediate gears whereby the driven gear will be caused to rotate alternately in 'opposite directions as the master gear rotates continuously in one direction, 'a swinging lever mounted upon the bracket, idler pinions carried by said swinging lever to operatively connect the gear on the-driving shaft with the master gear, and a latch carried by said swinging lever and adapted to engage said bracket.

In testimony whereof I affix my signature.

ERNEST B. GUSTOFSON. [L. 51.]
